[tahoe-dev] "tahoe stats" command

Hello Brian,

Which is a great feature to have, but for an end user hard to a)
verify and b) use as information. Especially since there is no
"count-files-duplicates" field.

OK, I have 991 duplicates of 850 files, consuming 678.13 mb, according
to DupFinder and to my embarrassment. Still, does not match.

Maybe when displaying information, a human-readable terminology would
be useful. Like "Files" means files that user will see on his hard
disk after restore, and maybe an entry "Duplicate files" or
"Duplicates found" can be added.

Them can you add "size-files" or "size-restored-files" or similar?

Consider a poor user with a job, trying to backup bunch of files to a
safe place. I do appreciate the developers need for "literal files",
but quite honestly, everybody else will wish they dont have to know
about them.

I would even suggest that 'stats' should print out only information an
(average) user expects: number of files, directories, sizes - as seen
on his file system. Instantly recognizable and verifiable.

The rest can become visible with 'stats --verbose'
